Views of a 3D object
Nets of 3D object
Surface area of a prism
Surface area of a cylinder
The front, back and side depend on the way the shape is shaping me.
The total of all the sides of a 3D prism.
A = LxW
If even sides are even then do it 2x
f/b = 11x5 = 55x2 = 110
t/b = 6x5 = 30x2 = 60
sides = 11x6 = 66x2 = 132
110 + 60 + 132 = 302cm
Area: A = π x r 2
Cercle + Rec: (2 x π x r2) + (2 x π x r x h)
Circumference: C = 2 x π x r
A = π x r2 ~ C = 2 x π x r
A = π x 102 = 314
C = 2 x π x 10 = 62.8
(2 x π r2)+(2 x π x r x h)
2 cercles + rectangle
2 x π 5 2 + 2 x π x 10 x 12
=910.6
